You will not see Emma Thompson in the upcoming "Love Actually" reunion, for a sad reason.

Many of the other cast members got together to film a mini-movie for Red Nose Day, a biennial U.K. telethon to raise money for the Comic Relief charity, which helps impoverished children and their families.

In Richard Curtis' 2003 cult romantic comedy and ensemble film "Love Actually" Thompson and Alan Rickman, played a husband and wife whose marriage is strained by his romantic feelings towards another woman. The actor died at age 69 in 2016 after a cancer battle. That film is one of nine films he and Thompson had appeared in together. The list includes three "Harry Potter" movies.

"Richard wrote to me and said, 'Darling, we can't write anything for you because of Alan,' and I said, 'No of course, it would be sad, too sad,'" Thompson told the Press Association in an interview published Friday.

"It's too soon. It's absolutely right because it's supposed to be for Comic Relief but there isn't much comic relief in the loss of our dear friend really only just over a year ago," she said. "We thought and thought but it just seemed wrong but to revisit the wonderful fun characters of Bill Nighy and Hugh Grant and Liam (Neeson) and all of that, that's fantastic but obviously what would he have done? Both of them would be in therapy by now and I would be working on some kind of ward. It was absolutely the right decision."

"You know dealing with Alan is very complicated, so not really," he said. "We're not [involving] everyone. We're doing about two thirds of people."

Aside from Nighy, Grant and Liam Neeson, other "Love Actually" stars set to take part in the charity show reunion include Keira Knightley, Colin Firth, Rowan Atkinson, Thomas Brodie-Sangster and Olivia Olson. The 10-minute film, titled "Comic Relief Actually," will depict the lives of the characters in 2017.
